PIPING SYSTEM FOR GAS DISTRIBUTION.

SPECIFICATION forming part of Letters Patent No. 680,346, dated August 13, 1901. Application Iiled August l1, 1900. Serial No. 26,635. (No model.)

To tZZ whom t may concern:

A Be it known that we, JOHN A. MosHER and WILLIAM S. HAMM, citizens of the United States, and residents of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Piping Systems for Gas Distribution, of which the following is a specification and which are illustrated in the accompanying drawings, forming a part thereof.

This invention relates to a piping system for the distribution of gases in connection with which there may occur an accumulation of liquid either from condensation or other cause-such, for example, as acetylene gas in which there may be some moisture carried over into the piping system and becoming condensed therein must necessarily be drained off.

The invention relates more particularly to the piping of buildings, and especially of railway-cars, as hereinafter fully described and as illustrated in the accompanying drawings, in which'- Figure lis a side elevation of a railwaycar, the car being shown in dotted lines and the piping system in solid lines. Fig. 2 is a plan view of the same. Fig. 3 is an end view of the same; and Fig. et is a detail elevation, partly in section, of the storage and drainage tank.

In applying the invention to a railwaycoach the generator (conventionally indicated at 102) may be located in any convenient position within the coach. A gas-pipe 1111 leads downwardly from the generator to and below the ioor of the car, connecting with a pipe 103, leading to a storage-tank 104., located beneath the car. From this tank a pipe 105 leads, preferably at the farther end of the car, connecting with a riser 106, leading to a pipe 108 at and, as shown, upon the roof of the car and communicating with short pipe-sections 109 110 111 112 113, more or less in number, which directly serve the several chandeliers or burners.

At 107 is conventionally shown the gas-regulator, which is interposed between the pipes 106 108, though it may be located at any convenient point in the system beyond the storage-tank.

All of the pipes in the distributing system are either vertical or inclined from the horizontal, thev pitch being toward the storagetank, so that any liquid which may accumulate in the piping system will find its way by gravity to this tank. Following the direction of movement of the gas, it will be seen that the pipe 114 leads downwardly, the pipe 103 is inclined downwardly from its connection with the pipe 114 to the storage-tank 104, the pipe 105 is inclined upwardly from the storage-tank to its connection with the pipe 106, which in turn leads upwardly, and the pipe 108 is shown as being inclined upwardly from its connection with the pressure-regulator107, following the curvature of the roof, toward the center thereof.

Immediately below the storage-tank 10i there is located a drainage-tank 115, connected with the storage-tank by means of a pipe 116 and provided with a drainage-nipple 117. The pipe 116 and the nipple 117 are each provided with valves 121 122, and upon the stems of these valves are mounted intermeshing geared segments 118 I119, so disposed that while the valves necessarily move in unison one closes as the other opens. A handle 120 is applied to one of the valves, as 122, for manually controlling the valves. In practice the valve 121 will remain open until the tank 115 becomes filled, and the valves are now turned so as to drain oif the contents of the tank 115. No vent is necessary in draining this tank, as it may be allowed to drain slowly, the accumulation of moisture within the tank 101 being so slight that if the valve 121 remains closed for a number of hours no harm will result.

While we have shown the system only as applied to a railway-coach, it is obvious that it may be applied to a residence or other building in like manner, a suitable tank being provided for receiving the liquid and all parts of the piping system draining thereto.

We claim as our inventiontion, a generator, a gas-receiving tank, a pipe two valves so that they move in unison to openthe one and close the other.
